the morning after a crazy raging night and when you wake up feeling still drunk, often caused from a gin bucket. Signs of a mcmorning include crackheadedness, slurs in speech also known as analexia, running uncontrollably into things, and laughing hysterically for no apparent reason. Also, the strangest occurrences that would otherwise never happen occur during a mcmorning where crackheads like you seem to appear everywhere. You know its a mcmorning when you watch a crackhead take down his pants in the middle of the street and shit on a wall, or when you find yourself brushing your teeth on a bench in the middle of a park, or when you imagine mcmonsters in the woods, AND when you wake up at the earliest hours of the morning to wake everyone else up to join you in the mcfun (at least 7 o'clock).
